The Anthill Promo Tile was originally available in the Petrichor Honeybee Expansion Kickstarter.

Shuffle the Anthill tile in with the chosen regular tiles for this game (before adding in any honey producing tiles, if using the Honeybee Expansion).

Once the tiles have been dealt out, place the 6 Ant tokens onto the Anthill tile.

Whenever water drops land on the Anthill tile, all empty ant tokens pick up one drop each.

If, during your turn, you have at least one drop on an Ant token (on any tile), you may move that ant, and its drop, to an adjacent tile.

Drops on ants get harvested (if they are on a tile that gets harvested), and they count as drops on the tile where their ant is. Once its drop is harvested, the empty ant is returned to the Anthill tile.
